PM Update: Light mixed precipitation to fade away, very chilly Friday

* Winter weather advisory for far southern suburbs thru 1 a.m. (map) *

The chance of meaningful precipitation in the immediate Washington, D.C. metro region is pretty much over as dry air has fought off the storm passing by to our south. Yes, some patchy light mixed precipitation is possible this evening (rain, sleet and/or snow), but with temperatures above freezing, few problems are expected. Colder (sub-freezing) air filters in later at night, with a wintry chill to close out the work week Friday.

Through Tonight: Except for our far southern suburbs - mainly south of Stafford and Charles county - precipitation is spotty this evening, with a mix of light rain, sleet, and/or snow. Little or no snow accumulation is expected. In places like Fredericksburg, St. Mary’s county, and southern Calvert county, mixed precipitation may change over to a period of steadier snow, with perhaps 1-2 sloppy inches (low confidence). All precipitation winds down by midnight or so. Overnight lows drop fall from 26-31 (suburbs-city). Locations (mainly well south of town) which do get precipitation may see some patchy black ice in the morning.

Friday: For the first time in a week (seriously), we have a sunny day. But it’s one of the colder days of the winter so far with highs mainly in the mid-to-upper 30s. It’s breezy as well, with winds from the northwest at 10-15, making it feel near freezing (or lower) much of the day.
